NOTE: The dual (+) and (-) sub-out terminals are paralleled internally and the combined load impedance should be taken into consideration when connecting multiple subwoofers.

EXTERNAL SYNCED BRIDGED

CONNECTIONS/SETTINGS

1.Input Signal—Connect these RCA jacks as described in the Front Panel Connection section of this guide.

2.SLAVE/MASTER Switch—

•Set the SLAVE/MASTER switch on the master amplifier to the MASTER position.

•Set the SLAVE/MASTER switch on the slave amplifier to the SLAVE position.

•Setting the SLAVE/MASTER switch on both amplifiers will automatically set the I/O RCA jack configuration according to each amplifiers slave or master designation.

NOTE: Amplifiers in this combination can only be connect- ed in matched pairs. Multiple Matched pairs may be added to drive separate subwoofer loads in a given system.

3.Phase Switch— Set the phase switches of all synced MASTER amps to 0°. Set the phase switches of all synced SLAVE amps to 180°. The master and slave amps must be set to the opposite phase mode in order for External Synced Bridged operation to work.

4.To Achieve Safe, Optimal Performance—The LPF, Bass EQ, and Subsonic Filter controls on all synced amps must be set to the same position.

5.Signal Connection—Connect an RCA cable be- tween the OUT RCA jacks of the Master amplifier and the INPUT RCA jack of the Slave amplifier as shown in Figure 6.

6.Subwoofer Speaker Connection—In this amplifier combination, the Subwoofer speaker terminals of both amplifiers drive common subwoofer(s). Use the follow- ing speaker connection diagram when connecting the subwoofers to the amplifiers. Connect the amplifiers speaker terminals to any combination of one or more subwoofers that results in a nominal impedance be- tween 2 and 4 Ohms. DO NOT connect loads of less than 2 Ohms when connecting to amplifiers in the External Synced Bridged combination.

WARNING: Two wires of 12AWG minimum must be connected between the negative sub out terminals of the MASTER and SLAVE amplifiers.

WARNING: The amplifier’s gain control is bypassed com- pletely in SLAVE mode. DO NOT move the MASTER/SLAVE switch to SLAVE position when the amplifier is connected and playing. DO NOT connect any signal source to the amplifier in SLAVE mode that exceeds 200mV.

PA400.1 specifications

The Polk Audio PA400.1 is a powerful and versatile monoblock amplifier designed to deliver high-quality sound for automotive audio systems. As part of Polk's PA Series, the PA400.1 is specifically engineered to provide robust performance, ensuring that your subwoofers produce deep, rich bass without distortion.

One of the standout features of the PA400.1 is its impressive power output. This amplifier provides 400 watts RMS at 2 ohms, making it suitable for driving a wide range of subwoofers while maintaining clarity and integrity of sound. It is also rated for 300 watts RMS at 4 ohms, allowing flexibility depending on your setup and matching the needs of various subwoofer configurations.

The PA400.1 incorporates advanced technology to optimize performance. Its class D design ensures high efficiency, resulting in lower heat generation and prolonged operation under demanding conditions. This technology not only maximizes power output but also allows for smaller and lighter designs compared to traditional amplifiers. The compact size of the PA400.1 makes installation easy in a variety of vehicles, from sedans to SUVs.

Another key feature is the amplifier’s signal sensing capability. It can automatically turn on and off with your vehicle’s audio system, which helps conserve battery life and ensures that the amplifier is only active when needed. This is particularly convenient for users who don’t want to deal with manual activation.

The PA400.1 is designed with built-in low-pass crossover settings, which enable users to customize the frequency response to suit their specific subwoofer’s characteristics. This ensures that only the desired bass frequencies are sent to the subwoofer, enhancing sound quality and reducing distortion. Additionally, the amplifier includes adjustable gain control for precise sound tuning in your vehicle.

Overall, the Polk Audio PA400.1 stands out as an excellent option for those looking to enhance their car’s audio system with powerful bass response. Its combination of potent power, efficient design, and flexibility make it an impressive choice for audio enthusiasts who want to experience their favorite music in a whole new way. Whether you're upgrading an existing system or building a new one, the PA400.1 delivers performance that meets the demands of serious audio fans.
